Description

Hot melt adhesive grip

This creation is related to the grip belt, especially a grip belt with hot melt adhesive.

As shown in FIG. 1 , the handle 10 of the conventional bat is composed of a grip portion 11 and a grip belt 13 for winding around the grip portion 11; wherein the grip The belt 13 is spirally wound around the grip end portion 11 from one end of the grip portion 11 toward the other end in the long axis direction, and a stacking slit 131 is formed in the spirally wound loop portion of the grip belt 13.

As shown in FIG. 2, it is another conventional bat grip 20 which is composed of a grip portion (not shown) and a grip belt 23 for covering the grip portion. Wherein, the grip belt 23 is in the form of a sheet and is looped from the long axial direction of the grip portion to form a joint slit 231.

In the actual assembly process, the handles 10 and 20 must be attached to the side of the grip portion to lay an adhesive or a colloid, and lay a The release paper or a protective paper is adhered to the adhesive surface; then, when the adhesive or glue of the grip belts 13, 23 is to be adhered to the grip portion 10, the laid release paper or protection is applied. The paper is detached, and the adhesive surface of the adhesive tape or the adhesive of the grip belts 13, 23 is exposed for subsequent bonding.

However, the grips 10 and 20 mentioned above are still somewhat unsatisfactory in the practical assembly process; that is, when the grip belts 13, 23 are spirally wound around the grip portion, When the adhesive or gel of the grip belts 13 and 23 is adhered to the grip portion 10, at this time, The release paper or protective paper laid on the adhesive or colloidal adhesive surface of the grip belts 13, 23 must be detached by an additional jig or a work method, which does make the application personnel inconvenient in the process operation. Especially when the grip belt itself is a tubular structure, and it is placed on the grip portion of the bat, and then the release paper or the protective paper is torn off, the operation process of the process is further improved. difficult. Therefore, as to how to effectively improve the aforementioned situations, it is the purpose of this creation.

In view of the foregoing, the purpose of the present invention is to provide a grip belt having a hot melt adhesive, which is combined with a grip of a club, a racket or a bat by a predetermined temperature heating reaction or thermocompression bonding. Because of this, the convenience of the processing personnel in the processing process is greatly improved.

In order to achieve the foregoing, the present invention provides a grip belt comprising: a tube body for being fitted to a grip of a club, a racket or a bat; and a joint portion which is covered by the loop The inner peripheral wall of the tube. The bonding portion has a first adhesive layer and a second adhesive layer; the second adhesive layer is interposed between the inner peripheral wall of the tubular body and the first adhesive layer, and the first adhesive layer is The hot melt adhesive is bonded to the grip by a heating reaction or a thermocompression at a predetermined temperature.

Preferably, the joint portion is plural and fits and adheres between the tube body and the grip, and each of the joint portions is disposed from one end of the tube body along a long axial direction of the tube body. And extend to the other end.

Preferably, the joint portion is plural and fits and adheres between the tube body and the grip, and each of the joint portions is circumferentially arranged along the radial direction of the tube body, and each of the joint portions The joining portions are arranged along the long axial direction of the tubular body.

In the following, the structural features of the present invention and their intended effects will be described in detail by way of the examples and the accompanying drawings. First, in the embodiments and drawings, the same reference numerals are used to indicate the same. Or elements, components, objects, structures, systems, structures, devices, processes, methods, or steps that are similar.

Please refer to Figures 3 to 5 first. The present invention provides a grip belt 3 comprising: a tube body 30 for fitting to a grip G of a club, racket or bat, for example : a grip of a hockey stick, a tennis racket or a baseball bat, and the inner peripheral wall of the tubular body 30 basically comprises, but is not limited to, a material or a member of the felt layer.

A joint portion 50 is attached to the inner peripheral wall of the tubular body 30.

The bonding portion 50 has a first adhesive layer 51 and a second adhesive layer 53, and the opposite side of the first adhesive layer 51 and the second adhesive layer 53 can be bonded, bonded or bonded to each other; The second adhesive layer 53 is interposed between the inner peripheral wall of the tubular body 30 and the first adhesive layer 51. And adhering and adhering to the felt layer member of the inner peripheral wall of the pipe body 30; and the first adhesive layer 51 is a hot melt adhesive, which is combined with the ball by a predetermined temperature heating reaction or thermocompression bonding. The grips G, the racket or the grip of the bat are combined with each other.

In the present embodiment, the hot-melt adhesive of the first adhesive layer 51 of the bonding portion 50 includes, but is not limited to, an ethylene-vinyl acetate copolymer EVA hot melt adhesive, a polyamido-based Polyamide hot melt adhesive, The rubber-based TPR hot melt pressure sensitive adhesive, the polyolefin-based Polyolefin hot melt adhesive or the moisture-cured polyurethane PUR hot melt adhesive; and the first adhesive layer 51 is at a predetermined temperature (generally between 60 degrees Celsius) After the heating reaction or the thermocompression bonding process between ° C and 300 ° C, the grip G can be bonded to each other. The second adhesive layer 53 of the bonding portion 50 includes, but is not limited to, a solvent-based adhesive tape, an emulsion adhesive tape, a hot melt adhesive tape, a calender adhesive tape or a reactive adhesive tape. The second adhesive layer 53 is for adhering to the inner peripheral wall of the tube 30.

In this embodiment, the significant feature of the prior art is that the first adhesive layer 51 of the bonding portion 50 of the grip tape 3 is in the relationship of the hot melt adhesive material. It does not have a viscosity before the heating reaction or the thermocompression bonding process, so that the user can easily and conveniently set the tube body 30 of the grip belt 3 to the grip of the club, the racket or the bat. Putting G; then, after a predetermined temperature (generally between 60 ° C and 300 ° C) heating reaction or thermocompression, etc., the first portion of the bonding portion 50 of the grip band 3 is The adhesive layer 51 can be combined with the club, the racket or the grip G of the bat, so that the grip belt 3 and the grip G can achieve a tight bonding effect.

Therefore, a significant difference from the prior art is that, in addition to the process of detaching the release paper or the protective paper, it is no longer necessary to assist the handle by an additional jig or a work method. Assemble the grip with the club, racquet or bat, and greatly enhance the applicator The convenience of the processing operation of the processing procedure is to achieve the intended effect and purpose of the creation.
